Find Help on Bash Built-in Commands

[@JeffSmithInStJacobs]

Generally I prefer shorter videos, although some topics merit longer discussions. One feature of theurbanpenguin, though, is now and then he'll throw something at us that I've never heard of before, but now find incredibly useful. One example is using "^" to modify a previous command (eg. ^status^restart^ ). I now use that dozens of times each day. Thanks, Andrew!

[@theurbanpenguin]

That is a good one. Thanks for the great feedback

I really hope you teach CompTIA Linux+, RHCSA, RHCE, etc etc - I'm amazed at your youtube content and lack of following - you make this all so easy and break down a lot of the things that are just glossed over for the beginners, making the whole *nix platform "impossible" for them - I love that you take the time to inform people and inspire others to pursue the technology, rather than just starting at the end of an incredibly complex scenario and just talking to it - we need more people like you, and more lessons like this, to get a larger adoption of things that just seem "black magic" or "off limits" - super easy, THANK YOU!

[@theurbanpenguin]

thank you

[@justme-iz7ec]

that was fantastic. I like the videos where you go through entire series of commands. Like the ones in your exam preparation series quite a bit. This was superb work still. I am yearning for Linux videos that introduce small to mid-size projects that beginners can do to use their Linux skills. I sincerely want to use what I learn but cannot think of what to do.

You are doing a wonderful job by giving Knowledge many thanks

[@theurbanpenguin]

Thank you. Nice to hear from you

[@vsExtra]

Short but dedicated to a very well designated piece of Linux are better. Thank you for this episode)

[@theurbanpenguin]

Excellent thank you

[@LVusaAPI]

We like any video you are creating Andrew

[@theurbanpenguin]

Thank you

[@umairbalani6133]

Really good video regarding small but important topic.

[@theurbanpenguin]

Thank you

[@cleightthejw2202]

I like videos appropriate to the issue. And some might very well may need a number of videos covering different parts of the issue. Though I do like truly informative and educating videos with those that get to the point in pretty quick time and do NOT unnecessarily repeat things. You videos are pretty good. I do look forward to them :)

[@theurbanpenguin]

Thank you for your insightful feedback

[@ramialdeeb7280]

ITS WORKING! nice job dude

[@theurbanpenguin]

Excellent

Is there a way to have more help details of the options of a command? Maybe with examples

[@NoEgg4u]

I used to struggle with some bash built-ins. And the bash man page is an ordeal, for certain built-ins. For example, try locating the "if" keyword within the bash man page. Or try the bash man page for the "command" built-in. You get a blizzard of matches. I did finally learn about the help command. It does, however, sometimes often different wording than what is in the bash man page. And before I discovered that "help" would list all of the shell built-ins, I discovered that the following command lists all of the shell built-ins: $ enable -a If there is a way to jump to the part of the bash man page where the built-ins are documented, I would appreciate learning how to get there. I also discovered that some built-ins also have commands on disk. For example, my MX Linux (Debian) distro has a /bin/ls executable. Is it there for backwards compatibility to ensure no failures with old scripts, from before "ls" became a built-in? Was there a time when "ls" not a built-in, and only /bin/ls existed?

[@theurbanpenguin]

For the man page try man builtins. I don't know of ls being a built in on any distro I have used. It is usually and alias. I suggest using the command: type -a ls . You can also use it on the pwd command which is duplicated: type -a pwd . The reason some commands are both a builtin and independent command is that not all shells will have all the builtins

[@NoEgg4u]

@@theurbanpenguin I got "ls" confused with "pwd" (because I am on a Windows computer at the moment, and wrote my comment from memory). It is pwd that is both a built-in and executable file.

[@BarcaLS]

Short topics and movies are better, just a pills of knowledge :)

[@theurbanpenguin]

Thank you

[@neelojp8460]

thank you so much :-)... Short vidoes are good, so short vidoes are good also for you for youtube ads, from 30min video create 3x10min video with part1..3. so for us is good and for you too

[@theurbanpenguin]

Mid roll ads are only in longer videos. But I see your point. Thank you 🙏

[@fastsatelite9077]

It works! Thanks a lot.

[@theurbanpenguin]

Great

[@mb_mobile49]

Shorter videos. However lengthier videos are fine if it doesn't make logical sense to create a series of smaller videos for a particular topic.

[@theurbanpenguin]

Thank you for your thoughts

[@MartinsTalbergs]

Topic: running linux on phone? Are we there yet?

[@theurbanpenguin]

Technically android is Linux. iOS is not far of. I am not sure about iOS but on android there is a terminal application to allow you access to the cli. I think Ubuntu used to have a phone version but not sure

[@MartinsTalbergs]

@@theurbanpenguin all this I knew, but there is more to it. Imagine the full opensource degoogled phone. Thats a dream.

[@richardgarrow9260]

Yes you can run linux on a iPhone through an app

[@yotsaton111]
